摘要
某绿色建筑住宅小区采用生物接触氧化工艺处理生活污水,出水氨氮、COD、BOD5质量浓度分别为3.98,38.69,12.3 mg/L,出水水质满足GB/T 18920—2002《城市污水再生利用城市杂用水水质》中城市绿化的水质要求。为使出水ρ(BOD5)≤10 mg/L,进一步满足冲厕和洗车的标准,研究提出了增设水解酸化池或改造现有生物接触氧化的建议。
Biological contact oxidation process was used in a green building residential community to treat sewage. The ammonia,COD,BOD5 concentrations of effluent were 3. 98 mg /L,38. 69 mg /L and 12. 3 mg /L respectively. The effluent quality could meet 'city miscellaneous water quality: city sewage regeneration'( GB /T 18920—2002),and be used for greening. In order to make the BOD5 lower than 10 mg /L,and further satisfy the flushing and vehicle-washing standard,two suggestions,build a hydrolysis acidification pool or improve the existing biological contact oxidation were provided.
